Abstract
Description
Technical Field
[0001] This utility model relates to the field of fish processing technology, and in particular to a freezing structure for fish processing. Background Technology
[0002] Fish freezing equipment is a device that rapidly freezes fish at low temperatures, making it suitable for long-term preservation and subsequent processing. Fresh fish are rich in water and contain various enzymes and microorganisms, making them highly susceptible to spoilage at room temperature. Freezing rapidly lowers the fish's temperature, inhibiting microbial growth and metabolism as well as enzyme activity, thus greatly extending the fish's shelf life. Even in remote areas lacking cold chain transportation and storage conditions, or in emergency situations, it ensures that the fish maintains good quality for a considerable period.
[0003] When freezing fish, they need to be placed properly on freezing containers, usually using special hooks or trays. Appropriate spacing should be maintained between fish to ensure smooth airflow. During freezing, the fish's position needs to be adjusted periodically to ensure even cooling and prevent localized over- or under-freezing. However, current freezing technologies for fish typically involve simply stacking or laying fish flat on shelves, then manually turning them periodically to try and ensure even freezing. When freezing large quantities of fish, this process is not only labor-intensive and time-consuming, but also prone to damaging the fish due to handling, affecting the product's appearance and quality. Furthermore, frequent opening and turning are detrimental to maintaining a stable low-temperature environment within the freezer. Utility Model Content
[0004] This utility model provides a freezing structure for fish processing to solve the problems in the background art.
[0005] The present invention adopts the following technical solution: a freezing structure for fish processing, comprising two symmetrically arranged fixed placement racks standing on the ground, each fixed placement rack having a set of mounting components on one side, the two sets of mounting components being horizontally corresponding between the two fixed placement racks; a drive connection component is installed between the two sets of mounting components, the drive connection component being rotatably installed between the two sets of mounting components, the working end of the drive connection component extending through the mounting components to the outside of one of the fixed placement racks; multiple placement components are installed on the drive connection component, the multiple sets of placement components being symmetrically arranged in pairs on the drive connection component, the multiple sets of placement components being spaced apart on the drive connection component, and the multiple sets of placement components being rotatably connected to the inside of the fixed placement rack; the multiple sets of placement components enable the orderly hanging and storage of batches of frozen fish.
[0006] Furthermore, each of the fixed placement racks is provided with a rotating connecting plate on one side. One end of the rotating connecting plate is rotatably mounted on the fixed placement rack, and the other end of the rotating connecting plate is connected to the drive connection assembly. The rotating connecting plate enables the drive connection assembly to be stably connected to the fixed placement rack.
[0007] Furthermore, each set of the mounting components consists of an extension connecting rod and a fixing plate. One end of the extension connecting rod is mounted on a fixed placement frame, and the fixing plate is disposed on the other end of the extension connecting rod. The extension connecting rod is hollow inside, allowing the working end of the drive connecting component to pass through. A placement groove is provided on one side of the fixing plate. When the two fixing plates are horizontally aligned, the placement groove in the middle position allows the drive connecting component to be rotatably mounted between the two fixing plates.
[0008] Furthermore, the drive connection assembly consists of a mounting plate, a rotating rod, and a rotating connector. The mounting plate is installed between two fixed plates and is rotatably connected to the two fixed plates in a placement groove between them. One end of the rotating rod is located in the middle of the mounting plate, and the other end of the rotating rod passes through the extension connecting rod and is located on the outside of the fixed placement frame. The rotating connector is located on the other end of the rotating rod on the outside of the fixed placement frame. The rotating connector can be connected to the drive device or manually rotated to provide driving force.
[0009] Furthermore, each of the placement components consists of a connecting block and a support rod. The connecting block is installed on the outer wall of the mounting plate, and when the mounting plate is located in the placement groove, the connecting block will be located outside the fixed plate. There are two support rods, which are symmetrically arranged on both sides of the connecting block, and the other end of each support rod is connected to the rotating connecting plate. Each support rod has multiple rotating grooves arranged at intervals, and a rotating block is installed in each rotating groove. Each rotating block is rotatably installed on the support rod through the rotating groove. Each rotating block has a hook at its bottom end, and each hook is used for placing fish.
[0010] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:
[0011] This application presents a specially developed freezing structure for fish processing, specifically addressing the challenges of uneven cooling and difficulty in manual adjustment during the freezing process. The structure comprises two symmetrical fixed racks firmly anchored to the floor of the freezer, compatible and ingenious mounting components, a drive connection component that rotates flexibly between the two mounting components, and multiple spaced-apart placement components that are rotatably connected to the inner side of the fixed racks. During freezing operations, operators simply suspend batches of fish to be frozen orderly on the placement components, then activate the drive connection component (which can be connected to an external automated power unit to operate at a preset stable speed, or switched to manual control mode for flexible rotation as needed). Once the drive connection component is running, it drives the placement components to rotate continuously and smoothly, causing the fish hanging on it to sway as if in a gentle breeze, constantly changing their cooling angle and achieving uniform cooling from all directions. In this way, the tedious operation of frequently opening the box and manually turning the fish in the traditional freezing method is completely eliminated. This not only greatly reduces the labor intensity of the operators, but also effectively avoids the temperature fluctuations in the freezer caused by frequent opening of the box, as well as the damage to the fish that may be caused by manual turning. It effectively ensures the efficiency and quality stability of fish freezing, and brings a brand-new solution to the fish freezing and processing industry. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0021] Reference Figures 1-5 This utility model provides a freezing structure for fish processing, including two symmetrically arranged fixed placement racks 1 standing on the ground. Each fixed placement rack 1 has a set of mounting components 2 on one side, and the two sets of mounting components 2 are horizontally corresponding between the two fixed placement racks 1. A drive connection component 3 is installed between the two sets of mounting components 2, and the drive connection component 3 is rotatably installed between the two sets of mounting components 2. The working end of the drive connection component 3 passes through the mounting component 2 and extends to the outside of one of the fixed placement racks 1. Multiple sets of placement components 4 are installed on the drive connection component 3, and the multiple sets of placement components 4 are symmetrically arranged in pairs on the drive connection component 3. The multiple sets of placement components 4 are also rotatably connected to the inside of the fixed placement rack 1. The multiple sets of placement components 4 can enable the orderly hanging and storage of batches of frozen fish, ensuring that the fish do not squeeze each other during the freezing process, that the cooling is uniform, and that the freezing quality is improved.
[0022] In use, this application involves first placing the entire freezing rack in a temperature-stable, spatially well-designed freezer, ensuring that the two symmetrical fixed racks 1 stand firmly on the ground, providing a stable foundation for subsequent freezing and storage operations. Second, the operator precisely and securely installs the drive connection component 3 into place using two sets of mounting components 2 on one side of the fixed rack 1. The design of the mounting components 2 ensures that the drive connection component 3 can horizontally and stably span between the two fixed racks 1, achieving a reliable connection. At this point, the drive connection component 3 can rotate smoothly around the mounting components 2. Next, multiple sets of placement components 4 are systematically installed onto the drive connection component 3. Because the placement components 4 are symmetrically arranged in pairs and spaced apart, they fully utilize space and facilitate subsequent batch hanging of fish. Furthermore, these placement components 4 are rotatably connected to the inner side of the fixed rack 1, providing a structural basis for subsequent adjustments to the fish's position. At the start of freezing and storage, if manual operation is used, the operator can periodically rotate the working end of the drive connection component 3 extending from the outside of one of the fixed racks 1, causing the entire drive connection component 3 to rotate slowly. As the drive connection component 3 rotates, the multiple placement components 4 mounted on it also rotate synchronously. The batch of fish hanging on the placement components 4 sway as if in a gentle breeze, continuously changing their cooling angle. After rotating a certain angle interval, such as 30-60 degrees, there is a slight pause to allow the fish to fully contact the cold air in the new posture, achieving uniform cooling. An automated power system can be configured, connecting a motor or other power source to the working end of the drive connection component 3. After the power source is started, the drive connection component 3 will rotate at a set speed, such as 1-2 revolutions per minute, driving the placement components 4 and the fish to change positions stably and continuously, ensuring that the fish are cooled evenly from all directions. During the freezing process, operators only need to check the freezing progress periodically and adjust the power source operating parameters or decide whether to end the freezing process according to the degree of freezing of the fish. As time goes by, through this dynamic freezing method, the fish can reach the required freezing temperature faster and more evenly, and finally complete the batch freezing operation of fish to obtain high-quality frozen fish products. This application solves the problems of uneven cooling, low freezing efficiency and easy crushing and damage to fish caused by randomly stacking or simply laying them flat on shelves in the freezer in the prior art.
[0023] Preferably, each of the fixed placement racks 1 is provided with a rotating connecting plate 11 on one side. One end of the rotating connecting plate 11 is rotatably mounted on the fixed placement rack 1, and the other end of the rotating connecting plate 11 is connected to the drive connecting assembly 3. The rotating connecting plate 11 can stably connect the drive connecting assembly 3 to the fixed placement rack 1.
[0024] During the operation of the freezing rack, the drive connection assembly 3 bears the weight of multiple placement components 4 and a batch of fish, and generates complex torque and tension forces during rotation. The rotating connection plate 11, acting as an intermediate transmission link, cleverly decomposes and transmits these forces to the fixed placement rack 1. Its rotating connection characteristics make the force transmission more uniform and stable, avoiding stress concentration that may occur due to rigid connections, and preventing damage or loosening of the connection parts due to long-term uneven stress. It ensures that even under long-term, high-intensity freezing operations, the connection between the drive connection assembly 3 and the fixed placement rack 1 remains as stable as ever, guaranteeing the continuity and reliability of the freezing process.
[0025] Preferably, each set of mounting components 2 consists of an extension connecting rod 21 and a fixing plate 22. One end of the extension connecting rod 21 is mounted on the fixed placement frame 1, and the fixing plate 22 is disposed on the other end of the extension connecting rod 21. The extension connecting rod 21 is hollow inside, allowing the working end of the drive connecting component 3 to pass through. One side of the fixing plate 22 is provided with a placement groove 23. When the two fixing plates 22 are horizontally aligned, the placement groove 23 in the middle position allows the drive connecting component 3 to be rotatably mounted between the two fixing plates 22.
[0026] The mounting assembly 2, consisting of the extension connecting rod 21 and the fixing plate 22, features a clever layout. One end of the extension connecting rod 21 is tightly connected to the fixed placement rack 1, while the other end supports the fixing plate 22. This simple structure effectively supports the drive connection assembly 3 without occupying too much space. Moreover, the hollow design inside the extension connecting rod 21 is ingenious, allowing the working end of the drive connection assembly 3 to pass through it, avoiding additional external channels or complicated bypass structures. This results in a simple appearance and compact internal structure for the entire freezer rack, making full use of limited space, and making it especially suitable for use in space-constrained freezers.
[0027] The placement slot 23 on the fixing plate 22 plays a crucial guiding and positioning role. When the two fixing plates 22 are horizontally aligned, the placement slot 23 in the middle forms a precise "slot," allowing the drive connection component 3 to easily and accurately engage and smoothly rotate during installation. During assembly, operators only need to align the drive connection component 3 with the placement slot 23 and gently push it in, eliminating the need for complex calibration or adjustment processes. This significantly reduces installation difficulty, increases installation speed, and ensures that the freezer rack can be quickly assembled and put into use.
[0028] During the freezing operation, the drive connection assembly 3 needs to rotate continuously and stably to ensure that the placement assembly 4 and the fish are cooled evenly. The mounting assembly 2 provides solid support during this process. The extension connecting rod 21 transmits the force from the fixing plate 22 and the drive connection assembly 3 back to the fixed placement frame 1. Its hollow structure ensures strength while maintaining good stability, preventing easy deformation under stress. The fixing plate 22, with its placement groove 23, tightly "holds" the drive connection assembly 3, preventing axial offset or radial sway during rotation. This ensures the smooth rotation of the drive connection assembly 3, thereby ensuring the stable operation of the entire freezing system and laying the foundation for high-quality freezing of the fish.
[0029] Preferably, the drive connection assembly 3 consists of a mounting plate 31, a rotating rod 32, and a rotating connector 33. The mounting plate 31 is installed between two fixed plates 22 and is rotatably connected to the two fixed plates 22 within a placement groove 23 between the two fixed plates 22. One end of the rotating rod 32 is located at the middle position of the mounting plate 31, and the other end of the rotating rod 32 passes through the extension connecting rod 21 and is located on the outside of the fixed placement frame 1. The rotating connector 33 is located on the other end of the rotating rod 32 on the outside of the fixed placement frame 1. The rotating connector 33 can be connected to a drive device or manually rotated to provide driving force.
[0030] The drive connection assembly 3 brings superior efficiency to fish freezing. Its core components work closely together. The mounting plate 31 is securely embedded in the placement slot 23 between the two fixed plates 22, achieving a flexible rotational connection with the fixed plates 22. This ensures that the operation is stable and does not wobble, laying a solid foundation for subsequent continuous and stable rotational operations. One end of the rotating rod 32 is precisely positioned at the center of the mounting plate 31, while the other end cleverly passes through the extension connecting rod 21 and extends to the outside of the fixed placement rack 1. It quickly and accurately transmits the driving force from the outside to the mounting plate 31, driving the assembly to rotate. During this process, the hollow design of the extension connecting rod 21 effectively avoids external interference, ensuring efficient and stable power transmission. The rotating connector 33 located on the outside of the fixed placement rack 1 can seamlessly connect to the drive device, opening a new chapter in automated freezing. By precisely controlling the speed and direction of the drive device, it can easily handle large-scale freezing tasks, greatly improving efficiency and saving manpower. It can also be switched to manual mode at any time, allowing operators to manually control the speed and direction of rotation based on the real-time freezing status of the fish, finely adjusting every detail to ensure that each fish is cooled evenly at the appropriate pace.
[0031] Preferably, each placement assembly 4 consists of a connecting block 41 and a support rod 42. The connecting block 41 is installed on the outer wall of the mounting plate 31, and when the mounting plate 31 is located in the placement groove 23, the connecting block 41 will be located outside the fixing plate 22. There are two support rods 42, which are symmetrically arranged on both sides of the connecting block 41, and the other end of each support rod 42 is connected to the rotating connecting plate 11. Each support rod 42 has a plurality of rotating grooves 43 arranged at intervals, and a rotating block 44 is installed in each rotating groove 43. Each rotating block 44 is rotatably installed on the support rod 42 through the rotating groove 43. Each rotating block 44 has a hook 45 at its bottom end, and each hook 45 is used for placing fish.
[0032] In this application, the design of component 4 has many ingenious aspects in the fish freezing process:
[0033] First, the connecting block 41, as the connecting part between the placement component 4 and the drive connection component 3, is precisely installed on the outer wall of the mounting plate 31. When the mounting plate 31 is embedded in the placement groove 23 of the fixing plate 22, the connecting block 41 is exactly on the outside of the fixing plate 22. This layout ensures that the placement component 4 is closely connected to the main structure of the entire freezing rack, providing stable support for the subsequent carrying of fish.
[0034] Secondly, the two support rods 42 are symmetrically distributed on both sides of the connecting block 41, which not only expands the freezing space, but also connects to the rotating connecting plate 11, so that the placement component 4 can maintain a stable structural shape when it rotates with the driving connecting component 3, avoiding shaking or imbalance.
[0035] Finally, a major highlight is the multiple rotating slots 43 spaced apart on the support rod 42, where rotating blocks 44 can rotate freely. This design simulates the effect of natural wind. When fish are suspended on hooks 45 at the bottom of rotating blocks 44, the rotating blocks 44 adaptively rotate within the rotating slots 43 as the drive connection assembly 3 rotates and the cold air circulates within the freezer. This causes the fish to sway slightly, allowing them to fully contact the cold air, thus accelerating the freezing process, achieving uniform cooling, effectively avoiding quality differences caused by slow local freezing, and maximizing the quality of the frozen fish. The hooks 45 provide a direct hanging point for the fish, facilitating batch operations and greatly improving the efficiency and convenience of freezing.
[0036] Furthermore, this rotating mounting method exhibits unique advantages once the fish is suspended on the hook 45. Regardless of how the support rod 42 rotates with the drive connection assembly 3, the rotating hook 45 will automatically adjust its direction on the support rod 42 due to gravity, always pointing downwards. This means that the fish can maintain a vertically downward posture during the freezing process and will not tilt or flip due to the rotation of the support rod 42.
[0037] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
